The permanent goal in the field of electrical power grids is to find new ways of transmission and distribution electricity in terms of low cost and reliable. Due to explosive growths in the power demand, deregulation, and distributed generation facilities, these systems are possible to be exposed to stability problems ever than before. Local and inter-area oscillations are important types of these problems which are the results of inadequate damping of the power systems. In energy systems, the oscillations can be observed as the swinging of parameters such as buses Voltages, phase angles, and real power on transmission lines, this is due to the normal change in the increase or decrease of sudden load or external changes fault occurs in a system. The essential purpose of this topic is to research the damping oscillations of both local and inter-area by a three popular the "Flexible-Alternating- Current-Transmission (FACTS)" devices a "Unified-Power- Flow-Controller (UPFC)", "Interline-Power-Flow-Controller (IPFC)" and "Back to Back High Voltage Direct Current (BTB-HVDC)". In addition, The Kundur 2-Area of power system offered to study and compares the operation of each device. In this paper, a simulation model was brought and applied to an electricity grid. Finally, the results of simulation clarified the performance of each device under the normal and abnormal circumstance that has been simulated on the proposed electrical grid.

Sharing information and data over unsecured channel is liable for stealing and attacking, as a result cryptography becomes one of the most indispensable issues that provides data authentication. In this paper, a new technique of digital signature scheme has been proposed which combines elliptic curve cryptosystem (ECC) with Ong, Schnorr and Shamir signature scheme (OSS). A self-invertible 4^4 key matrix will be used as apart from OSS signature equations which will increase the overall security and efficiency against cryptanalytic attack. Elaborated results in terms of implementation and security analysis are declared and approved its strength. The proposed technique can be used as a secure alternative protocol if known systems are broken.

Especially in recent years, the most important issues that attract attention in the energy sector are the renewable energy and renewable energy usage areas. In this work, the most important part of the proton exchange membrane fuel cells that supply energy by using hydrogen energy is produced. Due to its superior optic and electrical properties, porous silicon, which is the focus of attention in recent years, has been preferred as membranes and production has been completed using different steps from the literature. By saving time during production, easy and low cost methods have been preferred. In order to observe the fuel crossover performance of the porous silicon, was carried out the permeation of formic acid through porous silicon membrane. The wafer was used a boron doped p-type wafer with 0.001-0.005 Ωcm, <100> oriented, double side polished, 3.61 cm2 active area and 200 µm thick. The thickness of the silicon wafer was reduced to 180 µm and was determined by the fuel crossover performance.

In this paper, nonuniform transmission lines (NUTLs) are used to design various types of filters. The characteristic impedance of NUTL can be expanded as truncated Fourier series. The optimized values of series coefficients are obtained by some optimization process. The characteristic impedance can then be determined and the width of the structure can be obtained. The performance of the designed filters is assessed by the well-known software packages high-frequency structure simulator (HFSS) and computer simulation technology (CST).

Finding a minimal dominating set (MDS) is a popular problem in wireless sensor networks (WSNs) to provide routing and backbone formation. A self-stabilizing system can tolerate topological changes such as node and edge joining/leaving thus they are very suitable for fault-tolerant and reliable WSNs. In this paper, we provide an extensive performance evaluation of self-stabilizing MDS algorithms for WSNs. To the best of our knowledge, this is the first experimental evaluation study of self-stabilizing MDS algorithms applied in WSN domain. We implemented the algorithms on various node counts and densities, and compared the average energy consumption, wall- clock time, move count and dominator count of the algorithms. The comprehensive simulation results show that the Goddard's algorithm finds the MDS with about 8.8% lower move and 5.8% lower dominator node count while its theoretical move count bound is higher than Chiu's algorithm. Despite of lower move count, the simulation results shows that the energy consumption of Goddard's algorithm is up to 1.5 times higher than Turau's and 2.8 times higher than Chiu's algorithms. The wallclock time, move count and detected dominator count of Turau's algorithm are respectively 84%, 88% and 12% higher than Goddard's algorithm in the networks with 1500 nodes which confirms its 9n move count bound. These measurements reveal that Goddard's algorithm outperforms other algorithms in terms of dominator count and Chiu's algorithm has a better performance for other metrics.

Vertex cover (VC) is one of the most fundamental graph-theoretical problems and has been widely used in wireless sensor networks (WSNs), particularly for the link monitoring problem. It is well known that a solution to the independent set problem (IS), which is another fundamental graph-theoretical problem, is complement of a VC. Self- stabilization is an important concept for designing fault tolerance systems. There have been many self-stabilizing VC and IS algorithms in the field. Even though a self-stabilizing IS algorithm can provide VC solutions, it does not give a theoretical guarantee on approximation ratio. In this work, we focus on practical fault tolerance performance of self- stabilizing IS algorithms in case of a vertex cover problem, particularly link monitoring in WSNs. We implement all existing self-stabilizing VC and IS algorithms and make simulations assuming a WSN in which nodes run synchronously. Results show that self-stabilizing IS algorithms in general are able to find better covers than VC algorithms, as they provide roughly 15% smaller solution sets. Furthermore, IS algorithms that run under distributed scheduler converges to a desired configuration in considerably less number of rounds than VC algorithms.
